Features

Multi-parameter Real-time Display

The inline conductivity controller works with conductivity sensors to continuously monitor water quality, simultaneously showing conductivity, resistivity, TDS and salinity on the 3.2-inch LCD display.
Abundant Output & Communication Ports

Comes with 2 SPST relays for automatic control, two 4-20mA outputs and 2-wire RS485 digital interface supporting Modbus protocol for PLC/SCADA integrations.
Data Logging & Flexible Mounting

Built-in real-time clock and historical data recording functions, stored log data can be downloaded for quality traceability. Various mounting methods: cabinet panel mounting, wall mounting and pipe clamp mounting.

Application

The online conductivity controller is designed for continuous industrial water quality monitoring. Widely used in RO reverse osmosis pure water systems, circulating cooling water, wastewater treatment, desalination, aquaculture and chemical water processes. Its flexible mounting, Modbus communication and data logging function make it ideal for automated water treatment plants requiring data archiving and remote system integration.
